Influence of cenosphere surface modification and volume fraction on the solid particle erosion of cenosphere/epoxy syntactic foams is investigated. Fly ash cenospheres are used as filler in both as received and silane surface modified configurations. Erosion behavior is studied at room temperature for different impact angles (30, 45, 60, and 90 ) and velocities (30, 45, and 60 m/s). Neat epoxy shows the highest erosion rate compared with that of the syntactic foams. Results show a strong dependence of impact angle and velocity on erosion rate of syntactic foams. With increasing cenosphere content erosion rate decreases for all impact angles. Erosion rate decreases with increasing impact angle and with decreasing velocity. Good interfacial bonding of treated cenospheres enhances the erosion resistance. All the samples exhibit ductile erosive behavior, with maximum erosion at 30 . The velocity exponent and erosion efficiency parameters confirm the ductile behavior of syntactic foams. POLYM. COMPOS., 40:2109-2118, 2019

“…The primary factor that makes the cenosphere an interesting material for prospective applications is their spherical, thin-walled structure and desirable chemical compositions. All these variables are dependent on the solid fuel combustion method and composition [10,[15][16][17][18][19][20][21][22][23]. The colour and sphericity of the cenospheres are also dependent on the type of coal [1,24].…”

“…The selected physical and chemical properties of the cenospheres (Table 1) include the chemical compositions (Ta- ble 2) and phase compositions (Table 3), and which are presented below in the tables. By comparing the table data with the chemical and phase composition, it is possible to evaluate the properties of a change in the country of origin of the coal [1,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Given below, are selected properties of the cenospheres essential for the complementarity of this review.…”

Aluminum-silicate cenospheres are the most valuable residue present in fly ashes after combusting stone coal. Cenospheres are hollow bodies with desirable engineering properties, such as hardness, low bulk density and complete chemical inertness, thanks to which they can be used in biomedical engineering. The following review presents data on obtaining and processing the material, as well as potential biomedical applications.

Energy efficiency in buildings requires adequate materials for thermal insulation. Given the enormous number of buildings worldwide needing a retrofit to improve their energy efficiency, it is of capital importance to identify materials suitable for sustainable thermal insulation. Among the many available insulators, polyurethanes occupy a preeminent role, given their versatility and effectiveness, and are thus expected to be extensively used in retrofitting buildings for improving their energy efficiency. Herein, the currently available bio‐derived or recyclable polyurethane‐based composites, considering them as either foams (i.e., with gaseous filler) or fully solid (i.e., with solid filler) composites, are assessed. The first section of the review is devoted to bioderived PUs as matrices for thermally insulating composites; the second section focuses on bio‐derived/recyclable fillers adopted with PUs as matrices, with specific reference to silica‐based aerogels. The main issues of the surveyed bio‐based composites are analyzed, and the future prospects of these materials, that are actually sustainable but at the same time performance effective, are discussed.
